An aircraft location and identification system, including a first position determining portion located aboard a transmitting aircraft for determining a first set of present positional and tracking information is described relative to said transmitting aircraft. A transmitting portion is included for transmitting the first set of present positional and tracking information to a receiving aircraft. A second position determining portion, which is located aboard the receiving aircraft, determines a second set of present positional and tracking information relating to the receiving aircraft. A computing portion is located aboard the receiving aircraft and/or a ground based facility. The computing portion utilizes present and past values of the first set of present positional and tracking information to derive a corresponding first probabilistic future tracking configuration of the transmitting aircraft. The computing portion also utilizes present and past values of the second set of the present positional and tracking information to derive a corresponding second probabilistic future tracking configuration of the receiving aircraft.
